Our take on the FiiO KA2 Portable DAC Headphone Amplifier

The FiiO KA2 is a tiny plug-in DAC and headphone amp that connects to a Lightning port and outputs to a 4.4mm balanced headphone jack. It uses two Cirrus Logic CS43131 DAC chips and delivers 153mW into 32 ohms, with very low distortion and high signal-to-noise figures. It handles PCM up to 32-bit/384kHz and DSD up to DSD256. It suits iPhone owners with balanced 4.4mm headphones or IEMs who want cleaner, louder sound than the phone's own jack, and it is smaller and simpler than desktop-style dongles with displays and multiple outputs.

Questions and answers

Will the KA2 work with my Android phone or laptop?
No. This version has a Lightning input, so it is made for Apple devices with a Lightning port. USB-C devices need a different model.
Can I use regular 3.5mm headphones with it?
Only with an adapter. The KA2 has a single 4.4mm balanced output and no 3.5mm jack, so standard single-ended headphones need a 4.4mm-to-3.5mm adapter.
Is it powerful enough for over-ear headphones?
It delivers 153mW into 32 ohms, which is plenty for most IEMs and efficient headphones. High-impedance or hard-to-drive planar headphones may want a more powerful amp.
Does it support hi-res audio?
Yes. It decodes PCM up to 32-bit/384kHz and DSD64, DSD128 and DSD256, so it can play hi-res files from compatible apps.
What is in the box?
The package includes the KA2 host unit, an adapter and a user manual.
Does it need a battery or charging?
No. It draws power from the connected device through the Lightning connector, so there is nothing to charge.
Where is the FiiO KA2 Portable DAC Headphone Amplifier cheapest?
At Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders, for $35.38, as of our latest check.
